3. First French-German Conference on Research Based on Confidential
Administrative and Survey Data: IAB-CASD Cooperation

The IAB and the French research data center Centre d’Accès Sécurisé aux
Données (CASD) have recently established a cooperation for cross-country
remote access. The aim of the cooperation is to foster and facilitate the use
of confidential micro data from both countries and to improve the data sources
for comparative research in social sciences.

As part of this cooperation, the first French-German Conference took place in
Palaiseau, France on March 28th and March 29th 2019. Throughout the
conference, researchers and data producers discussed many different topics
relating to labor markets and the possibilities of cross-country research.
Keynotes by Olivier Godechot on segregation at work and Christian Dustmann on
the effects of lowering welfare benefits on migrants generated heated debates.
A concluding panel session highlighted the potentials and challenges of cross-
country research for France and Germany and presented different datasets
particularly suitable for this research. The panelists discussed the
possibilities for improving transnational access to confidential data and
emphasized the importance of cross-country cooperation.

Previous studies with a focus on the German crafts sector have used the older
Classifications of Occupations of the Federal Employment Agency (1988) and the
Federal Statistical Office (1992) in order to identify the population of
interest in the data. In 2010, a new German Classification of Occupations was
introduced. Here occupations are broken down into new- and fundamentally
different- levels and groups. This fundamental rearrangement requires a new
conception for the statistical delimitation of the German crafts sector. The
first qualified proposal was submitted in 2014 by the Federal Employment
Agency (FEA), which issued the lists of codes for several 'specific
occupational aggregates'. This Report analyses the structure of the new
classification, matches all occupational codes to the relevant groups
specified by the German Craft and Trades Code (Handwerksordnung), and provides
corresponding identification methods when using the labor market data of the
FEA and the Institute for Employment Research.

We want to remind that on-site or remote access to our data requires that our
users comply with our confidentiality requirements. Section 7 (2) of the use
agreement states:

'Weakly anonymous data and internal output must neither be copied in writing,
printed or photographed nor copied, duplicated or removed from the computing
environment of the FDZ of the BA by any other means. The dissemination of
weakly anonymous data or internal output via email, telephone, text messages,
fax or any other form of communication is prohibited.'

It is therefore not allowed to collect or make notes about individual data
points during the on-site stay within the do-files that will be sent to you.
The same rule applies for any output in JoSuA's internal-use-mode. This is
true even if your sole intend is to inform your co-authors (or even us!) about
certain aspects/problems you found in the data. If you want to discuss data
problems with us, please contact us beforehand and tell us about the general
problem. If the solution requires that you point us to specific cases, we will
advise you to do so without breaching your contract. In particular, please do
NOT send us (or others) any individual or establishment IDs, even if these IDs
are artificial numbers, or copies of data spells or full individual
biographies under any circumstance.
